I've recently acquired DVD Studio Pro 1.5 (for OS X), and I've placed the Quicktime export to MPEG2 file in the appropriate Quicktime folder on my Mac hard drive. When I open a Quicktime file and export to MPEG2, it will only allow the resolution of 720x480, but my source is 352x240. Increasing the resolution in this manner will make the video worse, not better. Is there a way around this 720x480 thing?
